17.4. Adding or Updating DNS Services After Installation
DNS can be configured as part of the IdM server installation, simply by using the
--setup-dns option. If DNS is not configured then, it can be configured later using the ipa-dns-install command.
The
ipa-dns-install command also updates the DNS services on the IdM server.
[root@server ~]# ipa-dns-install -p secret --ip-address=1.2.34.56 --no-forwarders
-pgives the password for the Directory Manager user in the 389 Directory Server. All of the DNS entries are stored in the LDAP directory, so this directory must be accessed to add the DNS configuration.--ip-addressgives the IP address for the master DNS server.--no-forwardersmeans that there are no forwarders used with the DNS service, only root servers. Alternatively, use the--forwarderoption to define a forward to use; to specify multiple forwarders, use the--forwarderoption multiple times.- Reverse DNS is configured automatically. It is possible to disable reverse DNS by using the
--no-reverseoption.If an existing reverse DNS zone is already configured, using the--no-reverseoption uses the existing reverse zone rather than creating a new reverse zone. - The IdM server, unless it is explicitly disabled, leaves a persistent search open with its Directory Server and capture any new zone changes immediately.
